One week later the ceph is still balancing. What worries me like hell is the %USE on a lot of those OSDs. Does ceph resolv this on it's own? We are currently down to 5TB space in the cluster. Rebalancing single OSDs doesn't work well and it increases the "missplaced objects". I thought about letting upmap do some rebalancing. Anyone know if this is a good idea? Or if I should bite my nails an wait as I am the headache of my life.
